-Ilion, in the county of Herkimer and State ofNew York, have invented certain new and useful Improvements in T *pe-Writing Machines, of which the following is a specification.

My invention relates to typewriting machines and more particularly to the escapement mechanism thereof; to means for transmitting motion from the finger keys to the escapement mechanism; to means for va ing the touch of the finger keys at will williout altering the feed action; and to line-lock mechanism. a

One of the main objects of my invention is to provide eflicient mechanisms of the characters specified and to render the machine as a whole more reliable, rapid and eflicient and to these and other ends which will herein after appear, my invention consists in the novel construction, arrangements and combinations of parts to be hereinafter described and claimed.

In the accom anying drawings, wherein like reference c aracters designate corresponding parts in the various views, Figure 1 is a central vertical sectional view of the machine taken from front to rear. Fig. 2 is a rear elevation of the same. Fig. 3 is a plan view of the machine. Fig. 4 is a detail rear elevation of the upper portion of the machine. Fig. 5 is an isolated detail side elevation of a portion of the escapement mechanism and the means for transmitting motion thereto from a finger key. Fig. 6 is a detail rear elevation of the escapcment wheel and the back stop pawl or the means for preventing a backward rotation of the escapement wheel when the carriage is moved from left to right.

Fig. 18 is a side elevation of the feed ogs, the dog carrier and an element of the line lock mechanism, the view being taken in an opposite direction from that of Fig. 12.

The invention is shown in its application to aNo. 6 Remington typewriting machine and in the drawings, 1 designates the framing of the machine which is surmounted by the usual top plate 2 andis provided with a fulcrum bar 3 that extends transversely across the machine and cooperates with the notched portions 4 of the key levers 5, each of which is provided at its forward end with a finger These key levers are restored to normal positions by springs 7 and are guided in their movements y combs 8 and 9. Each of the key levers is connected to a link 10 which in turn is pivoted at its upper end 11 to an arm 12 that extends from a type bar 13, each type bar being pivoted at 14 in a han er 15 secured to the top plate 2. Extending transversely beneath the various key levers and beneath the key levers 16 of the s acing key or bar 17-, is a universal bar 18. his universal bar. xtends beneath the various key levers near t 1e forward ortions thereof and is adjustab y connecter. t o-upwardly extending links 19 by thumb nuts 20 which are received on the threaded v ortions 21. of the links. The upper ends of t ie links 19 are pivotally connected at 22 to crank arms 23 that project from a rock shaft 24 that oscillates or turns in bearings 25 at the forward portion of the machine. This rock shaft extends transversely across the machine from side to side thereof, as illustrated in Fig. 2 and the links 19 are connected to the crank arms on the rock shaft near the ends thereof. A single centrally located crank arm 26 rojects downwardly from the rock shaft and is pivotally connected at 27 to a rearwardly extending link 28, the rear end of which is pivoted at 29 to one arm of a bell crank lever 30, pivoted at 31 to a bracket or hanger 32, that is secured in any suitable manner to the frame 1 of the machine. The other or rearwardly extending arm of the bell crank lever 30 is pivotally connected at 33 to an upwardly extending link 34, the upper end of which is pivotally connected at 35 to a crank arm 36 that constitutes a part of one member 37 of the line lock mechanism. This member 37 is apertured and is mounted loosely at itsapertured portion upon the rock shaft 38 of the dog rocker, said. shaft having coned ends 39 that are adapted to be received within bearings 40 which are in the nature of rods with oppositely disposed recesses in the ends thereof for the reception of the coned ends of the rock shaft. These rods 40 are received in apertures in the lugs 41 which extend rearwardly from the supportin plate or bracket 42 secured to the top plate bv screws 43 (see Fig. 1). The bearing rods 40 may be secured in the adjusted positions by screws 44 which are threaded in and extend through threaded openings in the lugs 41.

Rigidly secured to the rock shaft 38 is a feed dog carrier 45 that tapped to receive the stem of a screw 46, the stem of this screw 46 extending through an elongated opening 47 in the line locking clement 37, and the head of said screw bears upon the side of said element and thus secures the element and dog rocker in the positions to which they may be adjusted relatively one to another. The dog rocker is provided with an offset ear 48 that is tapped at 49 to receive the stem of a screw 50, said stem passing through an aperture in the relatively fixed feed dog 51 so as to rigidly secure the dog 51 to its carrier or dog rocker. When the dog 51 is secured in place the edge 52 thereof abuts against a shoulder or ortion 53 on the dog rocker and the fixed dog is prevented from moving relatively to the dog rocker. Laterally extending cars 54 project from the dog rocker and receive between them the loose or stepping dog 55 which is pivoted to the ears at 56. From an examination of Fig. 14, it will be observed that the pivotal center of this loose dog is o )posite the eveled portion thereof or .is on that side of the dog toward which it moves from the normal or engaged position with a tooth of the escapement wheel to the advanced position where it has to cooperate with the next adjacent tooth of the escapement wheel. In other words, the dog 55 is pivoted to one side of the vertical center thereof, and on that side toward which it moves from the full line to the dotted line position represented in Fig. 14. By these means I am enabled to provide a much shorter stepping dog than heretofore with the same or greater efficiency and without liability of the ste ing dog moving to a position where it will not extend in the path of the next advancing tooth of the escapement wheel in the operation of the machine.

It sometimes occurs that the wear on the abutment which limits the movement of the stepping dog toward the advancing tooth of the escapement wheel will permit the dog to be projected to a osition where it will not extend into the patli of the said advancing tooth. There is little or no liability of this occurring in the present construction and by reason of the peculiar manner of pivoting the feed or stopping dog. This dog is shown in detail in Fig. 11, from which it will be seen that a depending portion 58 extends therefrom. and is adapted to abut against the body of the dog rocker to limitthe move ment of the dog in one direction, as representcd in dotted lines in Fig. 14. The move ment of the dog in the opposite direction is limited by an abutment 59 on the dog which cooperates with the body portion 60 of the dog rocker, as reprcsented in full lines in Fig. 14. There is also the advantage in the provision of a short str ping dog that a more re id movement of the arts is provided; t e dog being consideralily shorter is moved with greater rapidity, notwithstanding the fact that the dog is stronger and more rigid by reason of the decrease in the length thereof. Fig.14showsthesepartsabouttwicc the actualsizc,wl1creas Fig. 1 shows 4 he stepping dog about three times the actual size.

From an examination of Fig. 1], it will be seen that the stepping dogis provided opposite its working face with beveled faces 61 and (Elwhereas the fixed dog is provided with beveled working faces 51"; The bevels 61 and 61 constitute rentrant bevels which enable the st-c ping dog to properly clear and avoid con. ict with the teeth of the cscapemcnt whccl during the movement of the dog rocker back to normal position. The bevel 51 on the working face of the holding dog affords an advance and quick let-off of the carriage. On reference to Figs. 12 and 13, it will be seen that the dog carrier 45 has a laterally extending lug 62 which is tadped. to receive the stem of a screw 63 and the stem of this screw passes through 0 enings in the enlarged ends of the leaf springs 64 and 65 and the head of the screw bearing on these springs securely unites the ends thereof to the dog rocker. These springs are likewise provided with enlargements 66 which have central perforations 67 therein to permit the rock shaft 38 to extend freely therethrough. The spring 64 is shorter than the spring 65 and the u per end of the spring 65 is bent at right ang es to its body portion at 68 and rejects through an opening 69 in the dog roclier, the free end of the spring bearing on the feed dog 55 and within the recessed portion 70 thereof so that the tension. of both springs is exerted to force the stepping dog from the full line position to the dotted line referred to, has

position represented in Fig. 14. B the employment of the two leaf s rings as shown,

I am enabled to. provide a exihleand reliaiile spring structure without the liability ofthe springs being broken, a difficulty which has presented itself heretofore in the employment of a sin is comparatively stifl" sprm The dog roc or 45 is tapped transve y for the reception of a screw stop" 71 which extends therethrough and is adapted -to cooperate with an abutment 72 that is in the nature of a plate secured to a lug 72 that extends from the bracket-like plate 42 '(seeFig; 12). The serew-stop'il and abutment 72 limit the throw of the dog rocker and the parts connected thereto in the forward movement thereof and also limit the downward movement of the universal bar connected with the do rocker. The looking element 37 is provided with a laterally extending our 73 (see Fig. 5) which is tap ed transversely to receive a screw-stop 74 t at extends therethrough and the forward end of which is adapted to bear upon-a shoulder or lug 75 which projects from the dog rocker 45 so that when the screw 46 is loosened the screw stop 74 may be turned to afford an adjustment of the line locking element 37 and the dog carrier relatively one to the other, after which the screw 46 may be tightenedand the arts secured'in the ad justed' position. e lug 75 hpreinbefore projecting from its forward face a. pin 76 which rejects into an o that extends throng one end of the orvifor;

leaf spring 77, the opposite end of this s mg being rigidly secured to the bracket plate 42 by a screw 78. The spring-is likewise a ortu-red intermediate of its ends for the e passage of the stem' of a screw 79 which is received within a threaded opening in the bracket plate and the head of this screw 79 bears upon the spring and aflor'ds a means for adg'usting the tenslon thereof. The tention 0 this spring 77 is exerted upon the dog rocker and tends to force it towards the rear of the machine around its pivotal center. By the employment of a s ring 77 of the character s own I am .eneb ed to secure an easier and more resilient or elastic action than with the coiled torsional spring heretofore in common use.

The arm 36 of the line locking element is provided with a bearing shoulder 80 in. the

2 extends. This hell crank lever is pivoted at 83 to the bracket plate 42 and the arm.81 constitutesa stop to limit the movement of the arm 36 in one direction and consequently irl'g arm 85 which has a disk-like weight 86 ath of which an arm 81 of a bell crank lever This weight o poses such motion b 7 its inertia only, an not by its gravity. \e inertia of theweight issubstantiallyequal to that of The-arm 81 or the lever 82 the dog rocker. 1s connected at 87 to one end of a. coiled contractilo spring 88,- the lower end of this spnng being connected at 89 to an arm 90 that projecfsirom a stem 91 that is seated in a bear- 11:?w1t-l11h :1. lug 92 (see Figs. 1, 2 and 4) and is a opted to turn therein, in order to adjust the tension'on the spring 88. The stem 90 and arm 89' may be secured in the ad'usted position by a set screw 93 the stem of w liichis received within a threaded o eni in a lug 92 and bears at its inner en against the stem 91. The free end of the arm 81 is adapted to rest upon a stop 94 which is in the nature of a plunger that is movable longitudinal and is rovided at its 'lower end with a nurled mod 95. This plunger is received and adapted to move ongrtudinally in a central opening that extends through the exteriorly spring 99. surrounds the plunger and 1s interposed between the knur ed headllli and. the nut-like head 98, on thd sleeve so that the .5: ring exerts a downward tension on the cam-likc'portions 102 on the up er end of the sleeve 96. If the knurled has. be released at this time'the spring 99 will tend to force the etc 94 to the lowermost positron re resented in Fig. 17, where the pins 100 W1 be seated within recesses 101 that correspond to those at the hi hest portion of the sleeve and the stop will is preventedfrom accidental displacement. A vertical adjustment cit-he sleeve 96 will vary the height of the stop 94 whether the latter be in the highest orthe lowest position to which it may be set in the sleeve 96. The purpose of this adjustment will hereinafter more clearly appear. The

art 82 is provided with anupwardly cxtcnd+ mgarm I03 and at the upper end of this arm is an interiorly threaded s eeve which reccives a screw-stop or abutment 105 that or stop 94. This plunger stop 15 pro- 7 may be adjusted in the sleeve 104 for purposes which will hereinafter appear.

- The feed dogs 51 and 55 coiiperate with the teeth of an escapement wheel 106 that is operativcly connected to a shaft 107 through the internnidiate pawls (not shown) in the usual manner. This shaft 107 carries a feed pinion 108 at its fm'ward end for cooperation with a feed rack 1011 that is connected to arms 110 pivoted at 111 to the carriage 112. The carriage may be of the ordinary construction and is provided with rollers 113 that bear upon a transverse rail 114 and a frontroller 115 which bears upon the shift rod 116. The usual platen 117 may be provided together with the guide rail 118. A step 119 of the usual or an preferred construction is carried by the carriage and (-ooperates with an adjustable step 120 carried by the rack or stop bar 121 that is mounted u on pins 122 and is adapted to receive a slight turning as well as a longitudinal movement and to travel for a limited distance with the carriage against the tension 01'' the spring 123, as in the No. 6 Remington machine. To the underside of this rack 1.21 is secured by screws 124a bracket 125 that carries at its extremity a housing 126 in which a so-callcd arrester 127 is adapted to move. This arroster. consists of a stem-like portion which extends through the,housing and has 'a head 128 at one end thereof to limitthe movement of the arrester in one direct-ion. The opposite end of. the stem is provided with an enlarged head 129 which is normally maintained in the projected position, represented in Fig. 9, by a coiled expansion spring 130 that surrounds the stem of the arrester and bears at one end 131 against the housing, whereas. the opposite end 132 of this spring bears against an enlar ed portion 133 of the stem which is receiver in an opening in the housing and adapted to' guide the arrester in its longitudinal movement within the housin'g. The enlarged head 129 of the arrester is adapted to be interposed in the path of movementof the abutment 84 on the other member of the line locking mechanism when the carriage has moved a predetermined extent fromrig'ht to left, as determined by the positioning of the adjustable stop. 120 and as clearly indicated in Fig. 4 of the drawings. Secured to the underside of the rack 12-1 by screws '134 is an abutment 135 which projects into the path of the screw stop or-abutment 105 and is adapted to cooperate therewith in the movement of the carriage from Fight to left. The parts are so posit. ned that just before the end of the line is reached the stop 11!) will contact with the step 120, thereby causin a slight longitudinal movement of the me bar 121. This movement of the rack bar will cause the abutment 135 to force the upper end of the arm 103 toward the left (looking from the front of the machine), thereby raising the arm 81 oil the stop 94, as represented in dotted lines in Fig. 4, so that the part is moved which constitutes a stop for limiting the movement of the part 37, the dog rocker and the universal bar to normal position. The spring 77 then becomes effective to move the dog rocker and the abutment 84 toward the rear of the machine and away from and out of the path of the arrester and to move tne universal bar up close to the key levers as shown in Fig. 5. A slight further movement of the carriage from right to left will'bring the enlar ed head .1 l9 of'the arrester in the path of tie abutment 84, as shown in Fig. 4, thus preventing further vibration of the part 37 and the dog rocker connected thereto so that further feed movement of the carriage is prevented and an actuation of the finger keys cannot take place by reason of the fact that the escapenient mechanism is locked against movement and conseqnentlythe' universal bar cannot be depressed from the position shown in Fig. 5 to which it has been elevated. By providing a spring pressed arrester of the ,character described, I am enabled to avoid the liability of the parts being blocked,

should the arrester be brought into contact with the side of the abutment 84 before the abutment can be moved out of the path thereof. Thus for instance, if the end of, the arrester should be brought to bear against the side of' the abutment 84 before the latter has an opportunity to move out of the path thereof, it will not block the operation of the parts but will merely tend to press the arrester against the tension of its spring 130 and the binding action is insufficient to prevent the abutnient 84 from being moved to the proper position away from the arrester or toward the rear of the machine. When it has been moved away from the arrester, the tension of the spring 130 on the latter will automatically interpose the enlarged head 129 of the arr'cstcr in the path of the abutment 84 so that an attempt to actuate a key will merely result in fore-in the abutment 84 1 against the arrester and a iurtherdepression of the keys cannot take place.

I have rovded hand operated means for releasing t e line lock mac anism after it has been automatically locked at the end of a line, which is determined by the setting of the adj nstable step 120. These hand operated means consist of a rod 136 .which extends beneath the top late 2 of the machine and moves longitudina ly in bearings 13? depending therefrom and projects forward through the flange in the'top plate at the front of the machine where a button-like head 138 is connected to the red. A coiled spring 139 surrounds the rod and bears at one end against a guide 137 and at its opposite end against a shoulder formed by the rear of the head 138 so as to maintain the parts in the normal osition with the head projected forward. he rear end ofthe rod 136 is bent u wardly to form an arm 140 (see Fig. 4) which arm is received within a slot in a depending braoket 141 secured to the underside of the sto rod 121 in the usual manner. A longitudinal movement of the rod 136 towards the rear of the machine will cause the stop rod to be turned on its pivot pins 122, thus moving the arrestcr out of the path of the part 84 carried by the locking element 37; the part 37 being no longer obstructed, it is free to vibrate and the depression of the key levers is permitted so that one or more additional characters may be written to complete the word or sentence or to insert a hyphen.

The actuation of the escapeinent mechanism affords a step-by-step feed movement of the carriage from right to left, the carriage being propelled in this direction by a spring drum 142 which is connected to the carriage by a band 143 in the usual manner. When the carriage is moved'from left to right the feed pinion 108 will be rotated but the escapement Wheel 106 is intended to remain fixed against movement at this time. There is, however, a tendenc of the pawls (not shown) which are contained within the housing 144 to carry the escapement wheel in a backward direction during the riding of the pawls over the cooperating ratchet wheel and through frictiona contact therewith. In order to prevent any backward movement whatever of the escapement wheel 106, I have provided a back stop pawl 145 that has a sleeve 146 projecting therefrom. This sleeve surrounds screw ivot 147 which takes at its lower end in a t readed opening in a bracket 148 and a washer 147 is inter osed between the head of the screw and the s eeve. A coiled s ring 149 surrounds this sleeve and is secure thereto at one end 150, whereas the opposite end of this sprin is secured at 151 to a lateral extension of. the bracket. The pawl 145 is provided with a depending lug 152 which is ada ted to abut against the bracket at 152 as il ustrated in Figs. 6 and 8, and to limit the movement of the pawl in one direction. The bracket 148 may be secured by screws 153 to a laterally projecting lug 154 that extends from the plate-like bracket 42. From an examination of Fig. 6, it will be seen that the pawl 145 is adapted to bear against the escapement Wheel m a direction at right angles to the plane thereof and that the cam-like portion 155 on the pawl is adapted to be operated upon by the edges 156 of the teeth of the escapcmentwheel and to deflect the pawl against the tension of its spring 149. As soon, however. as the-wheel rotates to. a position where one of the radial spams 157 at the base of the teeth of the cscapemcnt wheel is brought opposite to the engaging hook or nose 158, said nose will be forced intothe space, thus positively preventing a backward movement of the escapement wheel or a movement in the d1rection of the arrow in Fig.6. It will be seen that the pawl by reason of its engagement with the star wheel in a direction at ri ht angles to the plane thereof is maintains at all times in engagement with the star wheel, either frictionally, when the pawl bears against the side of the teeth or in ositive engagement in a recess or opening tween the teeth thereof, so that there is at all times a tendency to prevent any backward rotation of the escapement wheel during a movement of the carriage from left to ri ht;

In certain characters of t ewnting mmchines in use, considerable di culty has been occasioned when undue pressure was exerted upon the finger keys in the operation of the machine. is usually provided with alstop to 'mit its forward movement and the downward movement of the universal bar, but the undue ressure referred to resulted in springing the ey levers which tended to straighten the bent connecting links or wires between the key levers and ty e bars and this effected a; derangement in t e adjustment of the machine. This is especially true where a lar 0 size of the asket is correspondin ly increased and there is a eater inclination and the degree of bend o the connecting links between the key levers and type bars, By

number of type bars are employed and t e '5 arranging the universal bar near the front of the machine, or between the finger keys and connecting wires, in accordance with my present invention, I am enabled to over- 7 come the difliculties pointed out above by reducing the objectionable spring in the key '105 levers when the universal bar is arrested bv the stop 71 on the dog rocker contacting wit the cooperative stop 72, and the resistance of the universal bar at this point tends to lift the connecting links rather than to strain or straighten them, should there be any spring in the key levers. I am therefore enabled to provide an action for th'escapement mechanism which is less liable to become deranged or thrown out of adjustment and 116 which is more positive in its nature and accurate in operation than heretofore.

In such machines, the do rocker 85 B the construction shown and described,- am

likewise enabled to mount the feed dog l the machine and can therefore provide a" shorter dog rocker and much lighter escapement mechanism than was customary heretofore. This will be appreciated from an examination of Fi 4 of the drawings. will be understoor that by shortening thedistance between the rock shaft of the dog rocker and the escapement wheel. I am (anabled not only to provide a lighter escapement mechanism, but one which is rigid o 'with the Weight 86 notwithstanding the lightness thereof and which is quicker and more efficient than the heavier escapements with longer dog rockers heretofore employed.

From the foregoing description it wi ll be understood that when the finger piece '95 is adjusted so that the parts are normally disposed as shown in Fig. 1, the initial movement of the key levers and type bars indcpendently of the dog rocker or escapement mechanism affords an inertia of the/former to effect a movement of the latter and that an imroved easy touch on the finger keys t erefore results; It will also be understood that the weight 86 affords an inertia for the lever 82 which is substantially the same as the dog rocker and the movement of this weight in a horizontal direction obviates reaction of the lever by ravitation of the Wei ht and reduces the vi ration of the dog roc er to a minimum. Furthermore, the dog rocker spring and the sprin 88 being nearl though not quite of equa strength, the o rocker when in motion might overcome t e spring88 and the lever 82 would react more quickly, were it not provided and there would be a possibility of the carriage skipping a space without printing by reason of the spacing or feed dogs being ad usted to engage the teeth of the escapemen wheel a short distance that will not admit of any considerable or unusual vibration thereof without effecting a skippin movement of the carriage.

-n a justment of the sleeve 96 is ordinarily effected in the first instance primarily to regulate the height of the stop 94 when the latter is set in the uppermost position in the sleeve 96, in order to regulate the position of the dog rocker. Incidentally this regulation of the sleeve 96 also re ulates in part the position of the universal ar with reference to the key levers. If further regulation of the universal bar is necessar' to increase or decrease the lead of the way levers this may be effected by the thumb nuts 20. Thus, it will be seen that the sleeve 96 and thumb nuts 20 or both may be employed as conditions may dictate to determlne the extent of lead" or the extent of lost motion between the key levers and universal bar, whether the I stop 94 be set to bring the universal bar and ke levers into close proximity as indicated 5 or the stop 94 beset to afford a proiiounced lost motion as indicated in Fi 1. These adjustments being once effected it is ordinarily unnecessary to change them. In order to vary the touch of the finger keys within the limits determined by the adjustment of the stop 94 in'the sleeve 96, it is merely necessary to raise or lower the stop 94 through the knurled head 95. If, for instance, ,it be' desired to lighten the touch on the machine, it is merelv necessary to slightly raise the stop 94, at t e same tlme turning the knurled head and thus permit the pins 100 to be seated within the lowermost set of recesses 101 instead of the upper ones. This lowering movement of the stop 94 is effective to lower the arm 81. From an examination 10f Fi 5, it will be understood that a lowering ol the arm 81 lowers the arm-36 from the f u l to the dotted line position shown in that figure and that this movement will cause, through the intermediate link and bell crank connections, a lowering of the universal bar to the dotted line position and that thereafter the movement of the dog rocker and the parts connected thereto such as the universal ar will be limited in one direction, or in their return to normal position by the arm or stop 81 in its lowered position. A de res sion of the finger key at this time will a 0rd considerable lost motion of the key lever before it comes into contact with-the universal bar to move the esca ement mechanism, and an easier touch and me initial movement is thereby afforded. Furthermore, it will be observed that the lockingelement 84, by the movements of the arts just described, is moved from the full line to the dotted line position in Fig. 5 and the feed dogs and the carrier receive a like movement. This movement-of the feed dogs however, in no way affects the operation of the escapement mechanism, the construction and relation of the parts being such that it is merely a uestion of moving the feed dogs transversely of the rack to a greater or less extent depending upon the adjustment of the sto 94, and arm 81 and without changing the cod action of the escapement mechanism. In one case the feed dogs in the actuation of the machine, receive a transverse movement from an initial position which corresponds to that indicated :y the dotted line position of the part 84 in Fig. 5, and in the other case the feed dogs receive a transverse movement of greater extent and from an initial position that corresponds to the full line position of the part 84 in Fig. 5. In other words, an adiustment of the stop 94 causes the universe bar-to be taken up and the parts controlled thereby to be moved sooner or later in accordance with the adjustment of the sto thereb bringing about a change in the tone 1 of the nger keys without changing the feed action of the parts. The feed dogs always coiiperate to release the carriage at the same time, say, for instance, as soon as the finger of the operator starts to release the key, whether the feed dog carrier has a lon or short throw. In the event of the feed 0g carrier having a long throw the first art of the movement is inert and does not 0 ange the time of let-off of the carriage with relation to the release of the fin er he by the operator thou h the universe bar is taken up sooner and the do rocker and associated parts are moved furt ier and a heavier touch results.

Adjustment of the thumb nuts determines whether there is to be only a little or there is to be no lost motion whatever between the key levers and universal bar at this time. I prefer to adjust the thumb nuts 20 so that w en the part 84 normally stands in the full line position shown in Fig. 5 there will be a slight lost motion between the key levers and universal'bar. At this time the screw stop 105 carried by the arm 103 is in the furthest adjusted position towards the left (looking from the front of the machine) and when the parts are in the position described the arrester, or the head 129 thereof, will be interposed in the path 01" a part 84, during the travel of the carriage from right to left before the abutment 135 reaches contact with the screw stop 105 and there is no necessity for bringing the abutment 135 and stop 105 into play. This is because the adjustment of the parts described normally maintains the arm or part 84 in a position where there is no liability of it interfering with-the interpositioning of the arrester in its path and because there is little or no lost motion between the key levers and --universal bar and there is therefore no necessity of moving the universal bar up to compensate for the lost motion and thus prevent an appreciable depression of the key levers when the universal bar is locked against movement at the end of a line. When, however, the stop 94 is lowered to change or lighten the touch on the keys it permits a lowering of the'arm 81, thereby forcing down the arm 36 which results in dropping the universal bar to the osition shown in Fig. 1, thus creating. a 0st motion between the key levers and universal bar. This same movement of'the st o 94 results in bringing the part 84 of the ocking element further forward or towards the path of movement of the arrester with the carriage. The lowering of the arm 81 likewise advances the arm 103 so as to bring the stop 105 thereon further toward the right of the machine (looking from the front) and during the movement of the carriage from right to left the abutment 135 will reach contact with the screw stop 105 before the arrcster is interposed in the ath of the art 84 as indicated in Fig. 2.

he contact between the abutment 135 and the screw stop 105 is effective during a further movement of the carriage to rock the es bell crank lever, comprising the parts or position and there is In practice arms 85, 81 and 103, on its pivots 83, so that the arm 81 is automatically moved up to the dotted line position re resented in Fig. 4, thereby moving the universal bar up to the position shown in Fig. 5 to automatically take'up the lost motion between the key levers and universal bar. During this movement of the arm 81 the arm 36 follows it up and permits the part 84 to move back toward the rear 01" the machine, say to the fullline position represented in Fig. 5, where it will not obstruct the movement of the arrestcr and will permit, it to be interposed in the path of the part 84, as represented in Fig. 4, so that an attempt to depress the key lever at this time will cause the part 84 to be brought into contact with the head 129 of the arrester, thereby preventing a movement of the feed dog rocker and thus preventing a depression of the key levers by locking the universal bar-against movement in an elevated position where little or no appreciable movement oi the key levers can be effected.

From the foregoing description it la be understood that when the stop 94 is elevated, the arrester will be interposed in the path of the part 84 without actuating the mechanism automatically through'thc contact of the abutment 135 with the screw sto 105 and that when the part 84 is normally in the dotted line position the abutment 35 automatically bears upon the screw sto 105 during the movement of the carriage rom right to left and moves the part 84 out of the path of the advancing arrester so as to permit the 100 head 129 thereof to be interposed in the path of the part 84 and also automatically mo\ es the universal bar up to take up the est motion, and that this variation in the action of the parts is rendered necessary by the adios justment of the part 94 which sheets a change in the touch on the finger keys, because in one case the part 84 is normally clear of the arrester and in the other case the part 84 extends closer to or in the path of no movement of the arrester and in one case there is a material lost motion between the key levers and universal bar and in another case there is no lost motion or no material lost motion and when there is lost motion it is desirable to take it up in the line locking operation to prevent an appreciable key depression and a possibility of printing operations being effected through an attempted actuation of the keys at this time.

From the foregolng description it will be seen that the art 81 constitutes a stop for the universal liar to determine the normal position thereof and through which the normal position of the universal bar may be varied that said step is automatically controlled by the line look mechanism; that the osition of the stop may also be controlled y hand thrqugh the finger piece 95; that the automaticl operation of the stop 81 constitutes means for automatically taking up lost motion between the keys and the III- versnl bar as an end of a line is approached: that means are provided for locdng sail universal bar against movement alter said lost motion is taken up; that thestop 81 under certain circumstances arrests the univelsal bur (us shown in Fig. 1) before it reaches the end of its full return motion; that there are operative connect-ions between said stop and the line lock mechanism to move said stop before the line locki takes lace; that the stop 81 is controlled y the line lock sto 120, and that the automatic movement 0 the stop 81 is effected by the movement of the carriage.
